AEIO 580 UL unleaded fuel incompatibility
High Big Piston and KRviator, I checked the Lycoming service instruction pamphlet as per link, unfortunately my engine AEIO 580 does not qualify to use UL unleaded fuel,
Me and my friends have this engine on aerobatic aircrafts and we are worried, GAMI fuel should be compatible, though I don't even know if it is still at development stage and it would be available only in the US, Let's se what happens. Thank you for your asistance
